A new research has divulged that ‘Himalayan glaciers’ are melting twice as fast now as they were before the end of the century.
This research was published in Science Advances, which shows indication that climate change is eating the Himalayan glaciers and threatening water supplies for millions of people downriver over South Asia.
Lead author Joshua Maurer (a doctoral candidate at Columbia University in New York) said that this is the clearest picture, yet of how fast Himalayan glaciers are melting over this time interval, and why.
Researchers also go through 40 years of satellite observations. They have traversed 2,000 kilometres (1,243 miles) across India, China, Nepal and Bhutan, and found that each year since 2000, the glaciers have been melting (45 centimetres) of ice.
Maurer also said that Atmospheric warming appears to really be the dominant driver of ice loss. In inclusion he said that Himalayan glaciers may have lost as much as a quarter of their enormous mass over the past four decades.
Most of the 20th-century observations came from recently declassified US spy satellite imagery.
Rising temperatures are the biggest factor for melting glaciers. Although temperatures differ from place to place, an average temperatures were one degree Celsius (1.8 degrees Fahrenheit) higher between 2000 to 2016 than in 1975 to 2000.
Many other factors which researchers blamed were changes in rainfall, reductions tending to lessen ice cover, and the burning of fossil fuels, which lead to soot that lands on snowy glacier surfaces, absorbing sunlight and hastening melting.
A glaciologist at France’s Laboratory for Studies in Geophysics and Spatial Oceanography, Etienne Berthier (who was not involved in the study) said that It shows how endangered the Himalayas are, if climate change continues at the same pace in the coming decades.
Researchers are scaring that the melting of ice on the Himalayas will lead to change in the time and magnitude of streamflow in the populated Indian Subcontinent.
